Xu Shanshan has been persisting all along. She has become numb to the bugs and monsters; she kills the bugs casually and tries her best to avoid the monsters, not to confront them directly. If she can't, she resorts to firing her machine gun to temporarily drive them away.
But this method works fine with a few monsters. However, the numbers keep increasing as more of them emerge from the water. Xu Shanshan doesn't even know how many monsters are surrounding her now.
The monsters don't have any skills other than biting with their sharp teeth. They seem clumsy in movement, but when they bite, it's incredibly fast, like lightning. Initially, Xu Shanshan tried to jump over them using their backs, but she nearly got bitten. Knowing how quick her reaction time is, it demonstrates how dangerous this situation is due to the monsters' speed.
